SPECIFICATION forming part of Letters Patent No. 391,144, dated October 16, 1888.

Application filed June 1, 1888. Serial No. 275,707. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM D. HALL, of Beloit, in the county of Rock and State of Wisconsin, haveinvented a new and Improved Scallop-Turner, of which the following is a full, clear, and exact description.

This invention consists in a machine of special construction for doing various kinds of scallop-work or beading, asitis sometimes termed, substantially as hereinafter described, and pointed out in the claims.

Although the machine will here be described as applied to turning out the scallops on the flies of button and other boots, or turning out the scallops and edges of shoe uppers, in which the linings and outsides are firststitched together wrong side out and then turned right side out preparatory to a second row of stitching being put in, and is suitable for all scallops of button-flies or boot-tops of any design or shape, it is also and generally applicable to other kinds of scalloped work requiring to be turned, including the scallops on gloves and for turning out the fingers of gloves, which virtually are but elongated scallops.

Reference is to be had to the accompanying drawings,forming apart ofthis specification,in which similar letters of reference indicate corresponding parts in all the figures.

' Figures 1 and 2 represent vertical elevations, in planes at right angles with each other, of a scallop-turner embodying my invention. Fig. 3 is a side view of a scalloped button-boot fly, partly broken away, as the same comes from the stitching-machine, wrong side out. Fig. 4 is a similar view of the same fly after it has been turned right side out and the scallops partly turned out. Fig. 5 is a like view of said fly after the scallops have been all or fully turned out and pounded down, as usual, ready for the last stitching. Fig. 6 is a view in perspective of the Spreaders used for turning out the scallops and showing the boot-fly as in the act of having its scallops wholly turned out by saidspreaders; and Fig.7 is aperspective view, upon a larger scale, of the outer or working edge portions of the Spreaders, for the purpose of illustrating their irregular and reverse thicknesses, to prevent cutting the leather when the machine is at work, and to make the working-points or outer end portions of the spreaders of a uniform thickness when closed.

A is the base or table portion of the frame, which may be of any suitable construction, and upon which is mounted a standard, B, preferably of an upwardly-tapering construction. Riveted to the back of this standard is a stationary scallop-spreader, O, and pivoted to the opposite side of the standard, as by a screw, 6, is a second scallop -sprcader or spreader-lever, D, arranged to move laterally across, and with its upper working end portion close up to the adjacent upper end portion of the stationary spreader 0. When the two Spreaders G and D are closed one upon the other, with their upper edges or marginal portions in line with each other, the same constitute in effect the ordinary scallop-turning iron, and when in this position the same are used upon any part of the upper or goods under operation that is plain and where turning is needed.

The lateral or vibratory motion of the spreader D across the face of the other spreader, O, is produced by pressing with the foot upon a treadle, E, which is connected, as by a rod, 0, with a bellrcrank lever, F, having its pivot, as at s, and that in its turn is connected with the lower arm or leg of the spreader D by a lever, G, pivoted as at d. This serves to work the upper end portion of the spreader D laterally in the one or outward direction, as against the tension of a spring, e,whieh,when pressure is taken off the treadle, serves to return the spreader D to its normal or closed po sition in line with the spreader G. The spreader D has its lateral motion restricted or regulated by working in between oppositely-arranged adjustable stops or lug-screws ff.

By the lateral motion of the spreader D a most perfect, gradual, and easy-spreading action is obtained for the scallop. Thus, after the boot-fly Hin which 9 may indicate the lining and g the outside-comes from the stitchingmachine wrong side out, with a line of stitching, h, running in direction of the scal lops i, as shown in Fig. 3, has been turned by hand or otherwise right side out, as shown in Fig. 4, then said fly is subjected to the action of the spreaders G D, one scallop, i, at a time,

as shown in Fig. 6, by bearing down with the hands on the fly H, and simultaneously and uniformly working the spreader D laterally by pressing with the foot on the treadle E. This spreads the scallops as required, without stretching the leather, and turns each scallop out to its fullest extent as controlled by the stitching, leaving it perfect in shape, after which the scallops may be pounded down, as usual, ready for the subsequent or second stitching, as shown in Fig. 5.

The outer or working edges, k k, of the Spreaders O D are made thick, and their upper end portions of reversely-tapering thick nesses relatively to each other, as shown in Fig. 7, to avoid cutting the leather when the spreader D is Worked outward, and so that the spreaders present thin or opposite inner edges, in order that the outer end portions of the spreaders when closed will have a com bined uniform thickness.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a machine for turning and stretching out laterally the scallops or edges of boot-flies, shoe-uppers, and other turned work or articles, the laterally-expansible spreader comprising a support, a relatively-fixed member, and a relativelymovable member working transversely across the face of said fixed member, substantially as set forth.

"2. In a machine for turning and stretching out laterally scallops or for beading purposes, as described, the combination of the laterallyexpansible spreader, comprising a support, a fixed member, and a relatively-movable member pivoted to the face of the fixed member between the ends thereof to vibrate trans. versely across the same, with an operating mechanism connected with said vibratory member, substantially as set forth.

3. The combination, with theframe and an expansible spreader mounted thereon,andconsisting in a fixed member and a laterally-vibrating member pivoted to the face thereof,of an operating mechanism and stops in the path of the movable member to limit the length of its stroke in either direction, substantially as set forth. a

4. In a machine of the character described, a laterally-expansiblespreader comprising the stationary member, and a laterally-movable member pivoted together face to face, rounded at their upper ends, and made of an increased thickness on the opposite or working edges k is, and of diminishing thicknesses in reverse directions relatively to each other toward their opposite edges, substantially as set forth.

5. The combination, with the table having a standard on its upper side, of a laterally-expansible spreader comprising a stationary member secured to said standard, a laterallyvibrating member pivoted between its ends to the stationary member and extending at its lower end down and to the table, a spring. for returning the said'member to its normal position, stops in the path of the movable member for limiting its movement in either direction, a horizontally-swinging lever engaging with one end the lower end of the movable member to impart a lateral movement thereto against the action of the spring,a vertical bellcrank lever engaging the other end of the hori-. zontal lever, a treadle, and a rod connecting the treadle and the bell-crank lever, substantially as set forth.
